Clay bowl I made today. It's about 4.5" in length, 2" tall, and 1" thick. It's basically one big chamber. There is no draft hole. I have a carb on the left hand side, the bowl at the front, and the mouth piece at the back. It works great.
Be careful man. I had made a little firgurine and tried baking it in the oven when I thought it was dry, bbbuuttt it blew up because it wasn't dry enough. edit- clay dust and millions of little pieces of clay is not fun to clean from an oven, trust me.
